The Manley Performance Subaru WRX EJ205 piston set is engineered for high-performance applications, specifically for 2002-2005 Subaru Impreza and select Saab 9-2X models. Crafted from premium 2618 alloy forgings, these pistons deliver exceptional strength and durability necessary for demanding tuning and racing environments. Designed with proven cam and barrel skirt profiles, they optimize power output while maintaining gentle interaction with the cylinder walls for longevity and reliability. The pistons are equipped with moly skirt coatings on select part numbers, reducing friction and wear during operation.
This piston set features chrome moly wrist pins as standard, with options for higher-grade wrist pins made from 9310 or Turbo Tuff/DLC alloys, providing increased resilience under high-stress conditions. Unique fixturing technology allows for precise skirt turning and ring groove machining in a single step, ensuring perfect ring land and groove squareness. These features contribute to improved ring seal, enhanced compression, and ultimately, increased power output.
The cam and barrel profiles are carefully engineered to generate substantial power while minimizing stress on the cylinder walls, promoting engine durability. Designed to fit specific Subaru and Saab models, this set is ideal for enthusiasts and professional tuners aiming to maximize engine performance without compromising reliability. Please note that this product is not CARB approved and requires carb acknowledgment. It is suitable for air freight but not restricted, and it meets Prop 65 standards for safety. With one piston per package, this set is essential for rebuilds and performance upgrades seeking superior quality and engineered precision.
